The objective of this study is to evaluate the effectiveness of placing Traffic Calming Markings(TrCM) at different locations along the road to influence motorists’ speed, and provide an alternative to replace existing speed regulating strips on our roads. The study tested on 11 TrCM locations and the 85th percentile speed results showed that eight out of the 11 locations showed a reduction in speed while two locations have become ineffective and one location showed no change in speed. The results also indicated that TrCM was more effective when combined with other natural features such as a crest, a gentle bend or presence of a narrowing effect. However, it was less effective when applied along neutral road gradients and down slopes.
With this in mind, further tests were carried out to compare the effectiveness of TrCM before and along a bend. Concurrently, similar arrangement was also carried out to determine the speed for Speed Regulating Strips (SRS) before and along a bend as a means to compare the effectiveness between the two traffic calming measures. Thereafter, the findings on both of these speed tests would ascertain the appropriate locations to provide TrCM to reduce motorists’ speed and an option to replace SRS if necessary.
